摘　　要：介绍了空间前方交会法测量像控点的方法及其平差理论;以焦作市电视塔为例,利用所测像控点的3维坐标进行了数据平差计算和精度分析,得出空间前方交会法方案的可行性结论。This paper introduced the method of surveying image control point by making use of spatial forward intersection and it＇s adjustment theory. Taking Jiaozuo TV Tower as an example, it implemented the adjustment and accuracy analysis using the acquired 3D coordinate of image control points. Finally, it concluded the feasible result which makes use of spatial forward intersection to survey the image control point.
